Specification of Letters Patent. Patgnted NQV- 3Q 1915,

Application filed December 9, 1912. Serial No. 735,681.

I To all whom it may concern Be it known that I, HERBERT E. WHITE, acitizen of the United. States, residing at Youngstown, in the county ofMahoning and State of Ohio, have invented certaln new and usefulImprovements in Paint.

Spraying Devices, of which the following is a specification.

features of construction whereby the paint or coating medium can bequickly and effectively applied to bothsides of the expanded metalwithout excessivewaste of the paint.

It has been found impractical to use the ordinary spraying devices forpainting expanded metal or similar perforate articles, owing to the factthat much of the paint or coating medium passes through the perforations and is wasted, and among the objects of the present inventionis to provide a device in which this objection is overcome by oppositelydisposed nozzles which are arranged upon'opposite sides of the member tobe coated and produce jets which "meet in substantially the plane of thesaid member so as to produce a veritable atmosphere of the coatingmedium.

A further object of the invention is to provide a spraving or coatingdevice which is comparatively simple and inexpensive in itsconstruction, which is continuous in its operation, and which admits ofthe nozzles being readily adjusted so as to always obtain the bestresults.

With these and other objects in view, the invention consists in certainnovel combinations and arrangements of the parts as will more fullyappear as the description proceeds, the novel features thereof beingpointed out in the appended claims.

For a full understanding of the invention, reference'is to be had to thefollowing description and accompanying drawings, in which Figure 1 is atop plan view of a paint spraying device constructed in accordance withthe invention, portions being broken away. Fig. 2 is a side elevation ofthe same,

portions being broken away and shown in section, and Fig. 3 is atransverse vertical sectional view through the device.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Specificallydescribing the present embodiment of the invention, thereference character A designates an endless conveyer which may be of anysuitable construction and upon'which the expanded metal membersl areplaced. This conveyer A is shown as comprising the two chains 2' whichare connected by the transverse supporting rods 3 and pass around thesprockets 4 upon the shaft 5. Power may be applied to the shaft 5 in anysuitable manner for the purpose of driving theconveyer and carrying theexpanded metal members 1 thereon between the opposed upper sprayingnozzles 6 and lower spraying nozzles 7 'The upper and lower sprayingnozzles 6 and 7 are carried by a frame B through which the upper reachof the endless conveyer A passes. This nozzle carrying framev B issubstantially rectangular in shape and isformed with tubular end pieces8 and 9, the middle portion of the end piece 8 communicating with andbeing swiveled at 10 to a main air supply pipe 11, while in asimilarmanner the middle portion of the tubular end piece 9 communicates withand is swiveled at 12 to a main paint supply pipe 13. These two swiveledjoints 10 and 12 have an opposed relation and are in alinement with eachother so that the nozzle carrying frame B can be swung about asubstantially horizontal axis or an axis in the plane of the memberbeing coated.

The top and bottom of the nozzle carrying frame B each comprise a pairof tubular members 14 and 15 which are arranged side by side, the member14 communicating with the tubular end piece 9,

while the member 15 communicates with.

arm 17 will serve to supply Compressed air to the nozzles, the passageof compressed air through the nozzles acting in the usual" manner toproduce suction and eject the paint in the form of a spray.

The various nozzles 6 and 7 are pivotally mounted between the arms 16and 17 so as to turn freely about a horizontal axis or an axis parallelto the member 1 being-coated. This admits of the upper and lower nozzles7 and 8 respectively being adjusted upon the nozzle carrying frame B soas to operate in the most effective manner upon the expanded metal ormetal lath. As has been previously explained, the nozzle carrying frameB can also be tilted as may be required. In Fig. 2, the nozzle carryingframe B is shown by full lines in an 'upright or vertical position, andby dotted lines as tilted into an inclined position. This same figure ofthe drawing also serves to illustrate the manner in which the nozzlescan be adjusted with respect to the frame B, the said nozzles beingshown by lines as tilted into positions at an angle or inclination tothe plane of the frame B, so that the jets therefrom meet each other atan angle, and by dotted lines as swung into a directly opposed relation.

Thejets of paint or coating material from the upper and lower opposednozzles 6 and 7 meet' substantially in the plane of the expanded metalmember 1 so as to produce a veritable atmosphere of the coatingmaterial, through which the said expanded metal member is moved by theconveyer. Both sides of the. expanded metal member are thusefi'ectivelycoated, and owing to the opposed rial or paint is avoided.

relation of the, nozzles and the meeting of the jets in the plane of themember, the usual and objectionable waste of the coating mateswing thenozzles toward or away from the member being coated. e

'2. A device for coatingpxpanded metal and the like, includingoppositely disposed and adjustably mounted spraying nozzles arranged onopposite sides of the member to be coated so that the jets therefrommeet substantially in the plane of the said member, and a pivotallymounted supporting frame carrying the nozzles, the said support ingframe being adapted to be tilted about its axis to swing the nozzlestoward or away from the member being coated and the nozzles themselvesbeing adjustable so that the inclination thereof with respect to theframe can be varied.

3. A device for coating expanded metal and the like, including conveyingmeans for the member to be coated, a swinging frame mounted to turnabout an axis substantially in the path of the said member,and-oppositely disposed nozzles adjustably mounted upon the swingingframe and arranged on opposite. sides of the path of the member so as tobe moved toward and away from the same as the frame is swung about itsaxis,

' the jets from the nozzles meeting in the path a of the member so as toproduce an atmosphere of the coating material through which the memberis conveyed, and the inclination of the nozzles with respect to theframe being adjustable as desired.

a. A device for coating expanded metal and the like, including a frameformed with tubular end pieces connected by opposed sides, an a r supplypipe communicating with one of the tubular end pieces, a coatingmaterial supply pipe communicating with the opposite tubular end. piece,oppositely disposed nozzles mounted upon the sides of the frame andcommunicating with the respective tubular end pieces thereof so as toreceive a continuous supply of air and coating material, and means forsupporting the member to be coated between the nozzles. r

'5. A device for coating expanded metal 1 and the like, including aframe formed with tubular end pieces, an air supply pipe communicatingwith and having a swiveled connectlon with one of the tubular endpieces,

a coating material supply pipe communieat- .mg with and havmga swiveledconnection with the opposite tubular end pieces, the frame being adaptedto be swung about its swiveled connections with the air supply pipe andcoating material supply pipe, op- I posed nozzlescarried by the frameand communicating with the tubular .end pieces so as to receive acontinuous supply of air and coating material, and means for supportinga member to be coated between the nozzles.

" 6. A device for coating expanded metal and the like, including a frameformed with tubular end pieces and connected by sides,

the said sides being each formed with a pair I of tubular membersarranged side by side and communicating with the respective end pieces,a pair of tubular arms projecting from each side and communicating withthe respective tubular members of the sides, op- I positely disposednozzles mounted between the tubular arms, an air supply pipe incommunication with one of the tubular end pieces of the frame, a coatingmaterial supplv pipe in communication with theopposite T tubular endpiece of the frame, and means of a pair of tubular members communicafling with the respective end pieces,- an air supply pipe communicatingwith and having a swiveled connection with one of the end pieces, acoating material supply pipe communicating with and having a swiveledconnection with the opposite end piece, the frame being adapted to betilted about its connections with the air supply pipe and coatingmaterial supply pipe, a pair of tubular arms projecting from each'of theside pieces of the frame and communicating with the respective tubularmembers thereof, nozzles mounted between the arms so as to receive acontinuous supply of air and paint through the opposite tubular endpieces of the frame, and means for supporting a member to be coatedbetween the nozzles.
